To make the black and white contrast more intense. The printed pattern paper is attached to the screen which has been exposed to the photosensitive material, and the whole screen frame is placed in a professional exposure machine, and the black pattern is exposed through a professional GaN lamp to deposit gallium in a dark room environment. The lamp illuminates and decomposes with light; the black part blocks the iodine gallium light line, no reaction occurs, the mesh is soluble in water, leaving a net on the wire mesh; otherwise, the rest of the screen is penetrated by the iodine gallium lamp and sensitized The material reacts and the mesh is blocked.
